David "Fathead" Newman, the legendary Texas-born saxophonist and long-time Ray Charles bandmate, is spending four nights this weekend at Iridium Jazz Club. Many of his good friends will join him onstage for an early celebration of his 75th birthday. Fathead was Paul Schaefer's guest on the David Letterman show earlier this week. And he was Gary Walker's guest on WBGO's Morning Jazz show today.
